摘要： A dispersion stabilizer having a nitrogen-containing organic group and a water-soluble acidic substance are added to an aqueous medium. Into the aqueous medium, a monomer composition comprising at least a polymerizable monomer, an anionic polymer, a polymerization initiator and a colorant is added and dispersed therein into a prescribed particle size. The particles of the monomer composition are subjected to suspension polymerization. The resultant toner is caused to have a sharp particle size distribution and an improved anti-blocking property because of the combined effects of the dispersion stabilizer and the acidic substance contained in the aqueous medium and the anionic polymer contained in the monomer composition.
